The F test of sample variance may be performed if it is not known whether the two populations have equal variance. In this case the hypotheses are . A) H0: µ1 = µ2 H1: µ1 × µ2 B) H0: n1 = n2 H1: n1 × n2 C) H0: µ c 4.0 H1: µ 4.0 D) H0: a1² = a2² H1: a1²× a2²

The F test is used to compare two variances, so the null hypothesis (H0) should state that the variances are equal, and the alternative hypothesis (H1) should state that they are not equal.
